To examine the influence of stimulus significance on more sustained as well as transient aspects of electrodermal, cardiac (HR), and eyeblink response, a 21-sec tone was sounded in one ear or the other. A click occurred during many tones, and a light followed offset by 9 sec. Four groups were
The Spontaneously Epileptic Rat (SER), a double-mutant for tremor and zitter mutations, shows spontaneous occurrences of absence-like and tonic seizures. Several lines of evidence suggest that the combined effect of Aspa and Atrn mutations is the most likely cause of the epileptic phenotype of the
The ontogeny of epileptic seizures in spontaneously epileptic rats (SER; zi/zi, tm/tm) was studied by examining behaviour and electroencephalogram (EEG) simultaneously. Weight gain and survival time were also studied. Compared with the control Kyo:Wistar rats, SER showed a much smaller increase in
We present a 46-year-old man who developed repetitive focal tonic-clonic seizure-like involuntary movement in the left lower extremity after a left basal ganglia (BG) hemorrhage. His symptoms were induced only by voluntary movement of the left lower extremity and were followed by transient
BACKGROUND
Involuntary convulsive-like movements sometimes occur in patients with brainstem strokes. These movements vary in nature, frequency, and trigger, including fasciculation-like, shivering, jerky, tonic-clonic, and intermittent shaking movements. Some are interpreted as decerebrate postures
The necrosome is a protein complex required for signaling in cells that results in necroptosis, which is also dependent on tumor necrosis factor receptor (TNF-R) signaling. TNFα promotes necroptosis, and its expression is facilitated by mitogen-activated protein (MAP) kinase-activated protein kinase
OBJECTIVE
The innate immune system is our first line of defense against infection and injury, and responsible for initiating inflammatory and immune responses to resolve infections and repair injured tissues. This review focuses on the Toll-like receptors (TLRs) of the innate immune system and their
Tonic immobility (TI) is considered to be an innate fear response characterized by a temporary state of profound and reversible motor inhibition. TI occurs in a wide range of species in a predator-prey confrontation and is hypothesized to be a terminal defence response occurring when there is
A 40-year-old man was admitted after 8 months of speech disturbance and locomotive ataxia. He had no seizures, lightning pains, paresthesia, visual loss, bladder disturbance or rectal incontinence. He had never been neurologically or psychiatrically ill and had no history of syphilis. When the
Tonic rabbit femoral artery and phasic rabbit ileum smooth muscles permeabilized with Triton X-100 were activated either by increasing [Ca2+] from pCa > 8.0 to pCa 6.0 (calcium-ascending protocol) or contracted at pCa 6.0 before lowering [Ca2+] (calcium-descending protocol). The effects of,
A new mutant, the Wakayama epileptic rat (WER), exhibiting both spontaneous absence-like behavior and tonic-clonic convulsions, was identified in a colony of Wistar rats. To determine clear seizure characteristics of this mutant strain, we analyzed the mode of inheritance of the convulsion and
Generalized clonic and tonic seizure-like movements were observed during emergence from anesthesia with sevoflurane in a 32-year-old man. The movements lasted 40 sec and necessitated no therapy. There were no significant effects of the incident on the cardiovascular system, such as hypotension,
We have demonstrated that non-patterned electrical stimulation of the lumbar cord can induce stepping-like activity in the lower limbs of complete spinal cord injured individuals. This result suggested the existence of a human lumbar locomotor pattern generator, which can convert a tonic input to a
Neurosteroids are endogenous regulators of neuronal excitability and seizure susceptibility. Neurosteroids, such as allopregnanolone (AP; 3α-hydroxy-5α-pregnan-20-one), exhibit enhanced anticonvulsant activity in perimenstrual catamenial epilepsy, a neuroendocrine condition in which seizures are
Ginseng has been used for thousands of years in the East as a 'tonic', and in recent years its use has extended to Western society. In the light of the current interest in complementary medicine, we summarize the effects and purported mechanisms of action of ginseng and present two vignettes of its
